NURSERY-BATH THERMOMETER.

Application filed October 12, 1927. Serial No. 225,827.

This invention relates to improvements in the construction of what areknown as bath thermometers and has for its object to provide an articleof this character especially adapted for use in the nursery or childrensbath.

A further object of the invention is to provide the thermometer properwith a holder which when placed upon the water will float and at thesame time immerse the bulb of the thermometer beneath the surface of thewater. v v

A still further object of the present inven tion isto provide novelmeans of attaching the upright thermometer holder to the base portion orfloat thereof.

I accomplish these objects by means of .the device described in thefollowing specification and set forth in the claims and illustrativelyexemplified in the accompanying drawings in which Figure 1 is aperspective view of my improved bath thermometer; Figure 2 1s a detailview of the base of the float with parts in section and Figure 3 is amodified form of base or float.

Referring to the drawings, 10 denotes a wood base or float, preferablydisc shaped as illustrated in the drawings, having diametricallydisposed slot '11 projecting to points on each side of the center, eachend of the slot 11 being mortised to receive a dovetail tenon 12 of anupright standard 13, the material adjacent the tenon 12 being projectedthereover to provide a shoulder 15 to abut the face of the base 10 whenthe tenon is inserted. One wall of the slot 11 at the center thereof issemicircularly recessed to provide an opening 1st into which the bulb 15of a thermometer 15 projects, the stem thereof being carried onthe faceof the standard 13 by means of staples 17 which embrace the stem atspaced intervals and are driven into the wood standard 13 for support.The standard 13 of course may be of wood cut out of any shape, the

illustration showing a duckling which may I be decorated to attract achild and upon the surface of the body at each side of the stem of thethermometer 16 suitable degrees 18 are indicated.

As disclosediin Figure 3 the device may be made of hollow construction,e. grcelluloid, in which case the standard 13 is cemented to the hollowbase 10.

In use the device is placedupon the surface of water in the bathreceptacle and because of its buoyancy will float, the weight of thestandard 13 beingsuflicient however v to cause the base 10 to ride lowin the water thereby submerging the bulb 15 of the thermometer 16 andpermitting the same to render an accurate reading of the temperature ofthe water being tested. The device may be allowed to remain on the waterdur ing the taking of the bath, both to render amusement. for the childand to indicate to the nurse when; the water has become too cool for thechilds comfort and safety.

What I claim and desire to secure by Letter Patent is: i

1. A bath thermometer, comprising a buoyant flat disc shaped base memberhaving a slot therethrough provided with mortised ends and a recessatone side, "an upright standard having its end tenoned to fitthe slotand mortised ends thereof, a p01.--'

tion of the-upright. beingprovided with a shoulder to abut the face ofthe base when the upright isinserted, and a thermometer tube carried bythe face of the upright and having its bulb projecting into the recessedportion of the, slot in the base. i

2. A bath thermometer, as claimed in claim 1 in which the standard isoutlined to represent a figure, and the surface thereof at oppositesides of the thermometer tube is graduated to provide readings therefor.

In testimony whereof I affix my signature.

ARTHUR ZADEK.
